Description
Technical Field
The invention relates to the field of modified plastics, and particularly relates to a good-appearance high-glass-fiber reinforced nylon composite material as well as a preparation method and application thereof.
Background
With the rapid development of science and technology, more and more application occasions begin to adopt high polymer materials to replace metal materials, for example, high-strength nylon composite materials have high rigidity and high impact resistance, can replace metal materials, and have a great development space in the fields of automobiles, sports equipment, medical treatment and the like. However, the high-strength nylon composite material often needs to be added with high content of glass fiber (the content of the glass fiber is more than 30 wt%), so that the flowability of the nylon composite material is poor, the molded product has the appearance quality problems of serious surface floating fiber, roughness, poor glossiness and the like, especially when the product is a black part, the floating fiber is more obvious due to large color difference, and the appearance quality problem of the molded product is more serious along with the increase of the content of the glass fiber. This drawback directly limits the use of high glass fiber reinforced nylon composites in automotive exterior parts that have high requirements for mechanical strength and product appearance. Therefore, in the research direction of high glass fiber reinforced nylon, how to solve the problem of fiber floating on the surface of the nylon product and improve the apparent quality of the product becomes one of the difficulties and hotspots for research of various large modified plastic enterprises.
Currently, the following methods are generally used to improve the problem of floating fibers on the surface of nylon products: 1) The flow improvement auxiliary agent is added, such as nylon resin with lower viscosity or special lubricant is used for improving the resin fluidity, but the flow improvement auxiliary agent can cause the reduction of the impact resistance of the material, and meanwhile, the flow improvement auxiliary agent is mostly small molecular substances and has poor temperature resistance, so that the problem of thermal degradation can occur when a larger product is injection molded, the performance of the product is reduced, even carbon slag is degraded, and the actual use value is lost. 2) The special glass fiber is adopted, such as flat glass fiber, but the floating fiber improvement effect is not obvious, and in addition, the special glass fiber is expensive, and the cost performance of the product is not high. 3) The special additive capable of reducing the nylon crystallization temperature is adopted, for example, organic dye nigrosine is used, but the nigrosine has a very limited effect of improving fiber floating in a high-glass fiber filling system, in order to achieve a better improvement effect, the addition amount of the nigrosine needs to be increased to 2-3 percent or even more, moreover, the nigrosine is added, so that the nylon product has poor weather resistance in subsequent use, obvious color change and easy surface precipitation in a high-temperature and high-humidity environment, a new appearance problem is caused, and the product has large pungent smell, and cannot meet the use requirements of automobile plastic parts, particularly the smell grade requirements of automobile interior parts. 4) The appearance of the polyamide or the amorphous nylon (such as transparent nylon) with low glass transition temperature is improved by reducing the melting point of the polyamide, but the floating fiber improving effect is not good, and in order to achieve the ideal effect, the addition amount of the transparent nylon needs to be higher, so that the formula cost of the product is increased (the price of the transparent nylon is more than two times of that of PA 66), the processing fluidity of the material is reduced, the defects of underfilling, starving and the like of plastic products are caused, and when the addition amount of the transparent nylon is excessive, the heat deformation temperature of the material is easily reduced.
Therefore, through the formula design, the high-glass fiber reinforced nylon composite material with both cost and good appearance is obtained, and has high practical value for promoting the development of realizing the lightweight of the automobile by replacing steel with plastic.

Table 1 example high glass fiber reinforced nylon composite material composition ratio (parts by weight) and performance test results
Table 2 shows the composition ratio (parts by weight) and the performance test results of the high glass fiber reinforced nylon composite material in the comparative examples
As is apparent from comparative example 2 and comparative examples 7 to 10 in Table 2, in the high glass fiber reinforced nylon system with the transparent nylon added alone, only the glass fiber content is low (35 wt%, comparative example 2), the addition of a small amount of the transparent nylon can improve the apparent quality of the molded product, but with the increase of the glass fiber content, even if the amount of the transparent nylon reaches 20wt%, the apparent quality of the molded product of the obtained material is still poor (comparative example 9), and even the apparent quality is reduced (comparative example 10). From comparative examples 4 to 6, it is seen that the effect of improving the apparent quality of the high-glass fiber reinforced nylon system is very slight by adding the organic black master batch alone, even if the amount of the organic black master batch reaches 3wt%, the apparent quality of the reinforced nylon system is still very poor, the weather resistance is obviously poor, and the problem of surface precipitation at high temperature and high humidity is obvious.
The comparison of the test results of the example 1 and the comparative examples 1 to 3, the example 3 and the comparative examples 4 to 8, and the example 6 and the comparative examples 9 to 11 proves that the comprehensive performance of the reinforced nylon composite material is obviously better than that of the reinforced nylon composite material which is singly added with the transparent nylon or the organic black master by adding the transparent nylon and the organic black master at the same time. Compared with a system of independently adding transparent nylon, the method achieves the same apparent mass effect, and the using amount of the transparent nylon is reduced by at least half.
